    wow those are sizeable increased to speed or power. i wonder how expensive it will be with the euv layers.
  • Gondalf - Friday, April 5, 2019 - link

    I don't think so, looking at the chart 5nm is only less than an half node vs 7nm and a little more than nothing over 7nm+. Likely many will stay on 7nm+ or 7nm, both cheaper and with similar performance.
    Not impressed at all from this new node, thinked for few phone SOCs only unfortunately.
    At 5nm we need of new transistors to have real advantages.

    You clearly are not comprehending the die size reduction - hence the ability for higher yields. This and power consumption will be strong enough drivers for this process to take off.

    >the ability for higher yields
    That only happens after the process hits a point of maturity and is refined such that the expenses of manufacturing the wafer are suitably compensated by the inherent value gained by the chips on the wafer. The initial complexity of the shrink leaves most chips imperfect and inherently unusable after strict QA standards mark which chips are acceptable and which won't work.

    It took a really long time for 7nm yields to be good enough for public consumption, and we're still waiting for most of those 7nm products to hit the market. Intel's _still_ having issues with 10nm node yields.

    While 5nm wafers can yield "more chips" per unit wafer, they also cost more than 7, 10, or 14nm wafers. You need to basically hit a point to where manufacturing of 5nm wafers is more profitable than continuing to manufacture the lower density wafers which are very refined processes with very good yields. 5nm processes will _eventually_ hit good enough yields to replace those other process nodes, but that's going to take a long time. The article only details that TSMC is seeing some initial promise with their 5nm process.

    While NVidia GPUs or Apple big chips (iPad & possible laptop chips) are going to take a while to be profitable, AMD Zen3 chiplets on 5nm (45nm2) for higher performance/frequency EPYCs are going to be extremely profitable (a.k.a. "cheeplets").
    Since the chiplets architecture allows AMD to speed up core & io design and validation significantly we could probably see this by end of 2020 coupled with DDR5 and PCIe 5.0.

    For large SOCs - reducing their area by 1.8 times, on the same process, will improve yields (especially if the current yield is low).

    When ASML move to High Numerical Aperture EUV System - many of the error deviations will reduce over their existing system (although LERoughness could be the upper limit on yields).

    At that speed of progress you'll be browsing the Internet on a googol numbered Chrome version on a subPlanck constant process!

    Long live marketing blurbs!

    There are no more "new node" since 16nm from TSMC, every node since than has been an iteration of previous node. Trying to improve things step by step rather than the old "Intel" way of full new node. It is the same with 5nm. Once 5nm matures those 7nm customers will move to it.

    Not to mention you are getting a new quite a bit of area reduction and performance in only 12 months time.

    The 10 nm whose a full node but it didn't lived long enough nor whose adopted much so in industry it whose considered as half node, 7 nm is a full node and so is (at least based on press material) 5 nm. Real half node's are 14 nm, 12 nm based on 16 nm one. The new structure Gate All Around is being worked on and EUV will see it's full utilisation approximately at the same time, FF reached it's expected full potential with 7 (10 really) nm, 5 nm is stretch beyond expected.

    "Intel way"? Oh you mean like actually giving results instead of 5 years of delay.
  • Opencg - Friday, April 5, 2019 - link

    to be honest 15% performance increase IS impressive at this point. in case your werent following we are approching a wall where structures wont have enough atoms to provide statistical reliability outside of flawless fabrication. we may be lucky to see 30% more performance increase from all future shrinks combined. significant performance increases are going to come from other means from now on. if you were thinking that 15% seems low then you just arent informed
  • ZolaIII - Saturday, April 6, 2019 - link

    To get further performance and area improvements both new materials and structure of the gates are needed. Samsung for instance is working on cheap growing of Graphen (cheap enough to be used for battery cells but not neither perfect or big enough to make sizable wafer from it) and GAA structures while EAV which still has some error problems will reach its full potential in the future. I expect all three in next cuple of years & where we will go afterwards I really don't know.
  • Santoval - Saturday, April 6, 2019 - link

    "At 5nm we need of new transistors to have real advantages."
    TSMC will apparently not switch to GAA (Gate All Around) even at 5nm. I wonder if they saving that for the 3/4nm node.
  • Santoval - Saturday, April 6, 2019 - link

    p.s. SemiWiki has predicted Intel will probably switch to GAA-FETs at 7nm. They also predict TSMC will switch to GAA at <5nm. Samsung might delay the switch for the ~2nm node.
  • name99 - Monday, April 8, 2019 - link

    Yeah, keep telling yourself that right up till Apple ships the ARM Macs, faster than Intel, on TSMC 5nm...
  • Opencg - Monday, April 8, 2019 - link

    i mean 15% performance increase for well over 15% price increase is hardly a leap forward. so objectively consumers will see little to no value increase from process alone. arm could bring architecture performance increases but honestly this is doubtful. esp when taking into account apples obsession with writing new code for everything to force obsolesence. if they would take thier time to develop a longterm codebase then instead of redoing everything with stupid gimmicks every time then MAYBE i could take this bold claim of your seriously. but no. its apple. and the performance value will go backwards due to process. so like 99.9999% your wrong and a fanboy
  • Zoolook - Friday, April 5, 2019 - link

    Bigger "shrink" (area) than I'd suspected compared to the 7nm, good stuff, wonder who will be first Huawei or Apple?
  • Opencg - Friday, April 5, 2019 - link

    45% area shrink is about 25% closer elements.
  • Diogene7 - Friday, April 5, 2019 - link

    On a personal point of view, I find that TSMC 5nm node is quite a key technological milestone as it finally represent a more important usage of the off delayed EUV lithography in High Volume Manufacturing (HVM).

    It will still take several years and decades for the technology to mature, and then be routinely used by most foundries but it is very promising in terms of technologies that should appear between 2020 and 2040. I wish I would be born in 202O 😛...

    +1. Should be called EXCITING UV....

  • FunBunny2 - Friday, April 5, 2019 - link

    I wonder. how much of this manufacturing is independent of the principal tool makers, aka ASML? is this work a collaboration, or is TSMC going it alone?
  • Metroid - Friday, April 5, 2019 - link

    Intel still on 14nm and amd soon on 5nm, how stupid can this get? Amazing to see intel as big as they are very far behind the competition. The gap is becoming so big that makes me to think that intel was taken on a mass barter level 99 skill to never ever compete anymore.

    Most likely this 5nm is bigger than Intel original plan for 10nm... these X nm thing Are pure marketing and They have nothing to do with real size... but good that euv is getting ahead! It help making chips with less relayering.
  • Kevin G - Saturday, April 6, 2019 - link

    It is indeed mostly marketing at this point but I still would find it doubtful that Intel's 10 nm would be denser than TSMC's 5 nm node.

    The question is if Intel's 7 nm node is more dense than TSMC's 5 nm node. Also which one of those two would arrive first. Volume production of Intel's 10 nm hasn't begun with only a handful of low volume parts shipping.
  • 5080 - Friday, April 5, 2019 - link

    I think he meant higher density creates about 45% more chips per wafer compared to 7nm, so a higher yield per wafer. This should offset the higher cost per wafer compared to 7nm wafers.
  • Opencg - Saturday, April 6, 2019 - link

    assuming there are no buffer zones 45% area reduction is over 80% more chips per wafer
  • Calin - Monday, April 8, 2019 - link

    As chips are square or rectangular and wafers are round, producing smaller chips uses more of the "border area". And yes, 45% area reduction means the same chips only use 55% of the area used before, so you get close to double the number of transistors in the same wafer area
  • zodiacfml - Friday, April 5, 2019 - link

    Hey Intel, come on! Stop penny pinching! I want to see a good fight.
  • TristanSDX - Monday, April 8, 2019 - link

    Improvement in 80% more density and only 20% better in power do not look good. Designs will have to greatly reduce frequency to reduce power draw and total benefit will be just 50% more perf over 7nm. Adding high costs for design and manufacturing, this process won't be popular.
    NVidia rezlized that is is more economcal to design and make large GPU on old process, than smaller GPU on newer process. They will move to 7nm, only when it will be much cheaper than now and again they will make large GPU
  • Calin - Monday, April 8, 2019 - link

    You could do as Apple, and use twice the transistors run at 75% maximum frequency for the same total power (the power saved is out of proportion with the decrease in working frequency).
